antimony ethylene glycol used in the polyester production

Specifications 1. obviously speeds up the condensation reaction rate

2. catalytic activity surpasses other catalysts

3. white mini-crystal

Antimony ethylene glycol:Property: The white mini-crystal; can dissolve in the glycol; easy to absorb moisture in the air, and   need to be strictly kept sealed. Usage: Mainly used in the polyester production, such as bottle-grade, film-grade and textile chips. Package: · The product is kept sealed in the polyethylene container, NW 20 kg;                 · The product is kept vacuum in the aluminum-plastic composite bag, NW 25kg;                 · Every 36 barrels are palletized according to the international standard, NW 720 kg or 40 barrels, NW 1000 kg.
